IPTV can be installed on any of the newer, and even some of the older, VU+ receivers, as well as other Enigma 2 receivers.
If not using the receiver to view satellite, terrestrial, or even cable, television, you might as well go for a dedicated IPTV streaming device, capable of 4K streaming.

I bought my parents a Minix Neo U9h, a few years ago.
There are lots of guides, on youtube, for these devices, just decide what you want it for, and which suits you best.
